ている。2. Description of the Related Art Conventionally, as a waterproof connector using a crimp terminal, for example, one shown in FIG. 6 has been generally known. In this waterproof connector, the crimp terminal 30 is housed in the terminal housing portion 25 of the connector housing 24, and the waterproof rubber plug 26 has the insulated wire 21 inserted in a close contact state and closely fitted to the terminal housing portion 25. The terminal accommodating portion 25 is closed. On the other hand, the crimp terminal 30 is
An insulation barrel 30a, which is formed by stamping a conductive metal flat plate, and crimps a small-diameter tubular portion 28 of a waterproof rubber plug 26 together with the insulated electric wire 21 inserted into the tubular portion 28, and an insulating coating 21. And the wire bar 30c for crimping the exposed core wire 23.

されていた。Therefore, in the waterproof connector having the conventional structure, the waterproof rubber plug 26 blocks the water that tries to enter the terminal accommodating portion along the outer wall surface of the housing, and the insulation barrel 30a connects the rubber plug 26 to the outer surface of the wire. If it is pressed against the rubber plug, it will travel along the outer surface of the wire and the rubber plug 26
The crimping terminal has a good watertight structure because the crimping terminal blocks the water that passes through the wire insertion part and enters the terminal accommodating part.

Water (indicated by an arrow in the figure) permeates into the inside of the electric wire coating from the end of the electric wire connected to the electric wire, and also passes through the electric wire connecting portion which is crimped by the insulation barrel 30a, and the terminal accommodating portion 25 from between the core wires 23 It sometimes leaked into the house. As a result, a leak current may occur between adjacent terminals.

Although it was possible to consider that it would not come out, in such a structure in which the insulation coating and the core wire are integrally crimped, due to the difference in the crimping diameter, the electrical contactability at the crimping part of the core wire is poor and the reliability is low. There was a problem that it lacked.

First, since the waterproof rubber plug 6 is attached to the insulated wire 1, the insulated wire 1 is inserted into the wire insertion hole 9 of the rubber plug 6.
Through the insertion hole 9 and project from the small-diameter cylindrical portion 8. The protruding electric wire 1 is peeled off in a state where the insulating coating 2 extends from the tip of the small-diameter cylindrical portion 8, and the core wire 3 is exposed at the end portion.

0b, the insulating coating 2 extended from the tip of the rubber plug 6 and protruding is arranged, and the core wire 3 exposed from the insulating coating 2 is arranged on the wire barrel 10c. Then, both barrels 10b and 10c are swaged together. As a result, since both barrels 10b and 10c are provided in a continuous and integral shape, the end portion of the insulating coating 2 and the core wire 3 can be substantially wrapped so as to be in an unexposed state as shown in FIG.

収容部への洩れ出しを防止する作用も併せ有している。The operation of both barrels 10b and 10c will be described in further detail. As shown in FIG. 4 (A), the wire barrel 10c having a barrel length longer than that of the newly installed barrel 10b is crimped at the tip of the barrel 3 to form the core wire 3. It is designed to bite deeply into the inside, whereby the electrical connection with the core wire 3 effectively works. Further, since the paste-like sealing material 11 is filled in the gap between the core wires 3 by pressure bonding, increase in contact resistance at the pressure bonding portion is prevented, and high electrical contact reliability is secured. Moreover, this sealing material also has the function of blocking the water penetrating between the core wires and preventing the water from leaking from the terminal tip portion to the terminal accommodating portion.

The insulating coating 2 and the core wire 3 can be pressure bonded together. By wrapping the end portion of the insulating coating 2 in the terminal, it is possible to prevent water from flowing out from the end portion of the coating 2. Finally, the waterproof connector is an insulated wire 1
At the same time as inserting the crimp terminal 10 connected to the terminal accommodating portion 5, the rubber plug 6 is fitted into the terminal accommodating portion 6 for assembly.

る。As described above, according to the terminal processing structure and the terminal processing method of the present invention, the crimp terminal is
Since the boundary portion between the core wire and the insulating coating, including the core wire of the insulated wire, is not exposed by wrapping it in the terminal, it prevents the flow of water that permeates the coating and leaks from the boundary portion. Leak current can be prevented from occurring. Further, by increasing the contact resistance caused by caulking the insulating coating and the core wire together, by filling the caulking portion with a sealing material, high reliability can be secured. In addition, the filling of the sealing material fills the gap between the core wires, thereby preventing the intrusion of water and providing a perfect waterproof connector.
